I've been using Adobe Premiere Elements 12.0 for about 2 years on a number of devices. I've just bought myself a new home/music studio machine - Dell XPS 8900, i7-6700k Skylake, 16GB RAM, Realtek sound card, dual video (vga displays) one running from VGA port on NVidia Ge Force 645, the other running VGA from the displayport from the onboard INtel HD Graphics card.

Anyway, on the new machine, I'm seeing issues with playback freezing every 20 or 30 seconds randomly, at which point I have to start it up again.

It's a bit irritating when trying to proof watch a section, but not the end of the world.

I've tried rendering, using a different soundcard, unplugging the audio (I read about some Realtek issues), uninstalling and reinstalling the program. Nothing has worked yet.

When you add a video to the beginning of your timeline, are you seeing a yellow-orange "render" line along the top of the timeline? If yuo're seeing this over your first video clip, it would indicate that your project settings are not matching your video specs.

OK, for anyone with the same issue. I solved mine by changing away from the Realtek onboard sound device. I've just run through the same video for an hour with no stops.

I know that Realtek has caused issues in the past from my reading on this subject and it has certainly proved the case with me. It's a terrible sounding device anyway, so moving my PC audio on to the sound card that I normally reserve for my recording studio work is a bonus.
